Definitions
- the present invention relates to a method for preparing aqueous furnish to be used in paper or paper board manufacturing.
- fillers For economical reasons, the trend in paper industry is to increase the proportion of filler in paper products and thereby to reduce the use of fibres. In addition to low price and good availability, fillers also increase the printability and optical properties of paper. However, a problem related to the increasing of the filler proportion is that the filler addition leads to a deterioration in the mechanical properties of the paper product. These mechanical properties of paper depend on inter-fibre bonding, and fillers inhibit partly this inter-fibre bonds formation due to their rigidity and poor capability of hydrogen bond formation. Increasing the binding between fibres and fillers is thus essential to improve the strength of filled paper. Furthermore, better affinity between the fibres and the fillers will also lead to a better retention of fillers.
- a publication EP 1936 032 A1 discloses a method of producing a laminate paper comprising at least two layers, said method comprising (i) providing an aqueous suspension comprising cellulosic fibers (ii) adding to the suspension microfibrillar polysaccharide in an amount to yield from about 0.05 to about 50 wt percent based on the weight of the cellulosic fibers (iii) dewatering the obtained suspension and forming a first layer having a density from about 150 to about 500 kg/m 3 of said laminate paper product
- a publication WO 00/47628 A2 discloses a method for producing derivatized microfibrillar polysaccharide, where the electrostatic forces are provided by anionic charge or by a combination of both anionic and cationic charge, by stabilizing and/or microfibrillating a polysaccharide starting material.
- the aim of the invention is also to provide a novel method for preparing a furnish in order to improve the interactions between fibres and fillers.
- the method according to the invention for preparing aqueous furnish is characterized in what will be presented in the characterizing portion of claim 1.
- the invention is based on the modification of the fibre and/or filler surfaces in such a way that the fibre-filler bonding will be enhanced, because the poor capability of fillers to form bonds with fibres is greatly responsible for the low retention of fillers and for the loss of mechanical properties of filled paper.
- at least the filler surface is modified by adsorption of cationic polyelectrolyte and nanofibrillated cellulose (NFC) during the furnish preparation. This modification creates a bilayer of cationic polyelectrolyte and NFC around the fillers, which improves the affinity between fillers and fibres.
- the fibre surfaces can be treated equally by forming the bilayer of cationic polyelectrolyte and NFC around the fibres.
- Filler and/or fibres are treated with cationic polyelectrolyte and nanofibrillated cellulose during the furnish preparation.
- the modification can be carried out in different ways.
- the treatment of the filler with cationic polyelectrolyte and NFC can be carried out by mixing the filler with the cationic polyelectrolyte and NFC before adding them to the fibre suspension.
- the modification of the fibre and filler surfaces can be carried out at the same time in the fibre suspension without separate mixing steps, or the fibre surfaces can be treated with cationic polyelectrolyte and NFC before the addition of the filler to the fibre suspension. It is also possible to treat filler and fibres separately one with cationic polyelectrolyte and other with nanofibrillated cellulose.
- the way of the modification can be chosen according to the convenience, for example based on the existing paper mill layout.
- One alternative way is to modify the filler surfaces by forming cationic polyelectrolyte and NFC bilayer as described above and in parallel, to modify the fibre surfaces by adsorption of cationic polyelectrolyte, because the adsorption of cationic polyelectrolyte on fibres increases the strength of inter-fibre bonds and increases the affinity of the modified filler to the cellulose fibres. Therefore, the modification of filler surface by cationic polyelectrolyte and NFC combined with the modification of fibres by cationic polyelectrolyte enhances significantly the filler-fibre bonding and thus the filler retention and the mechanical properties of the final paper product, particularly in Z-direction.
- cationic polyelectrolyte is cationic starch.
- the filler In the furnish preparation, at least a part of the filler conventionally used is replaced with the filler containing cationic starch and nanofibrillated cellulose absorbed to the surface of the filler.
- the furnish can also contain other fillers, sizing materials and additives as known by a skilled person in the art.
- the filler and/or fibre surfaces are modified by adsorption of cationic polyelectrolyte and nanofibrillated cellulose (NFC) during the furnish preparation in order to improve the interaction between fibres and fillers.
- NFC nanofibrillated cellulose
- the modification of filler and/or fibre surfaces can be carried out by mixing them with cationic polyelectrolyte and nanofibrillated cellulose.
- the filler and fibres are treated first with cationic polyelectrolyte and secondly with nanofibrillated cellulose by adding them to the fibre-filler suspension.
- the filler is treated with cationic polyelectrolyte and nanofibrillated cellulose before adding it to fibre suspension.
- the filler is preferably treated first with cationic polyelectrolyte and secondly with nanofibrillated cellulose by adding them to the filler suspension.
- the fibres can be treated with cationic polyelectrolyte before adding the modified fillers to the fibre suspension in order to increase the strength of inter-fibre bonds.
- nanofibrillated cellulose refers to a collection of isolated cellulose microfibrils or microfibril bundles derived from cellulose raw material. Nanofibrillated cellulose have typically high aspect ratio: the length might exceed one micrometer while the number-average diameter is typically below 200 nm. The diameter of nanofibril bundles can also be larger but generally less than 5 ⁇ m. The smallest nanofibrils are similar to so called elementary fibrils, which are typically 2-12 nm in diameter. The dimensions of the fibrils or fibril bundles are dependent on raw material and disintegration method. The nanofibrillated cellulose may also contain some hemicelluloses; the amount is dependent on the plant source.
- Nanofibrillated cellulose can also be directly isolated from certain fermentation processes.
- the cellulose-producing micro-organism of the present invention may be of the genus Acetobacter, Agrobacterium, Rhizobium, Pseudomonas or Alcaligenes, preferably of the genus Acetobacter and more preferably of the species Acetobacter xylinum or Acetobacter pasteurianus.
- Nanofibrillated cellulose can also be any chemically, enzymatically or physically modified derivate of cellulose microfibrils or microfibril bundles.
- the chemical modification could be based for example on carboxymethylation, oxidation, esterification, or etherification reaction of cellulose molecules. Modification could also be realized by physical adsorption of anionic, cationic, or non-ionic substances or any combination of these on cellulose surface.
- the described modification can be carries out before, after, or during the production of microfibrillar cellulose.
- Nanofibrillated cellulose can also be called nanocellulose, nanofibrillar cellulose, cellulose nanofiber, nano-scale fibrillated cellulose, microfibrillar cellulose, cellulose nanofibrils (CNF) or microfibrillated cellulose (MFC).
- nanofibrillated cellulose produces by certain microbes has also various synonymes, for example, bacterial cellulose, microbial cellulose (MC), biocellulose, nata de coco (NDC), or coco de nata.
- Nanofibrillated cellulose described in this invention is not the same material as so called cellulose whiskers, which are also known as: cellulose nanowhiskers, cellulose nanocrystals, cellulose nanorods, rod-like cellulose microcrystals or cellulose nanowires.
- cellulose whiskers also known as: cellulose nanowhiskers, cellulose nanocrystals, cellulose nanorods, rod-like cellulose microcrystals or cellulose nanowires.
- similar terminology is used for both materials, for example by Kuthcarlapati et al. (Metals Materials and Processes 20(3):307-314, 2008 ) where the studied material was called "cellulose nanofiber” although they clearly referred to cellulose nanowhiskers.
- these materials do not have amorphous segments along the fibrillar structure as nanofibrillated cellulose, which leads to more rigid structure.
- the filler can be any filler used in paper manufacturing, e.g. precipitated calcium carbonate (PCC), ground calcium carbonate (GCC), kaolin, talcum or gypsum.
- PCC precipitated calcium carbonate
- GCC ground calcium carbonate
- kaolin kaolin
- talcum kaolin
- talcum kaolin
- talcum kaolin
- talcum kaolin
- talcum gypsum
- PCC precipitated calcium carbonate
- the filler is added to the furnish in an amount of 1 to 60% by the dry weight of the fibres in the furnish, preferably 20 to 40% by the dry weight of the fibres.
- the nanofibrillated cellulose is added in an amount of 0.01 to 20% by the dry weight of the fibres in the furnish, preferably 1 to 10%, and most preferably 1 to 3%.
- Cationic polyelectrolyte can be any retention or strength polymer used in paper manufacturing, e.g. cationic starch, cationic polyacrylamide (CPAM) or polydimethyldiallyl ammonium chloride (PDADMAC). Also, the combinations of the different polyelectrolytes can be used. Preferably, the cationic polyelectrolyte is cationic starch (CS).
- the cationic polyelectrolyte is added in an amount of 0.01 to 5% of dry weight of fibres in the furnish, preferably approximately 2 to 4%.
- the furnish prepared by the method according to the invention can be used as such in paper or paper board making.
- the furnish can also contain non-treated fillers and other components, including e.g. conventional auxiliary agents and retention agents.
- the filler modified with cationic polyelectrolyte and nanofibrillated cellulose can be used in combination with conventional untreated fillers in filled paper grades.
- the furnish prepared by the method according to invention is used for manufacturing of a paper or paper board product.
- the furnish is fed into a forming section and water is removed from the furnish by allowing the furnish to drain through a water permeable forming wire, and after that, the paper web thus produced is dried and finished to produce a final paper or paper board product with good mechanical strength properties and a high filler content.
- Dried hardwood (birch) bleached chemical pulp was used in the experiments. About 360 g (o.d.) of pulp was soaked overnight in 5 l of water and beaten for 50 minutes at a consistency of 1.6% in a Valley beater (ISO 5264-1) to the Shopper-Riegler (SR) number (ISO 5267-1) of about 42. Afterwards 2 l of water was used to remove the last fibres remaining in the beater and added to the fibre suspension. This suspension was fractionated in a Bauer McNett classifier (SCAN-CM 6:05) using a 200 mesh wire to remove the fines fraction. At this point the SR number was about 18.
- the pulp was washed, first by acidic treatment (0.01 M hydrochloric acid) to remove metal ions and afterwards the fibres were converted to sodium form with 1 mM of sodium bicarbonate. After these two treatments, the pulp was washed thoroughly with deionised water.
- fractioning and washing were done in order to prevent possible interference of varying fines content, pH or salts that would hamper interpretation of the results.
- the filler was commercial scalenohedral precipitated calcium carbonate (PCC). According to the manufacturer, the average particle size of this PCC was 2.3 ⁇ m, the brightness 95% and the dry matter content was 19.9%.
- PCC commercial scalenohedral precipitated calcium carbonate
- NFC Nanofibrillated cellulose
- Nanofibrillated cellulose was obtained by high pressure homogenisation of fully bleached softwood including an enzymatic pre-treatment step.
- the principles of this approach have been published in Pääkkö, et al., Enzymatic hydrolysis combined with mechanical shearing and high pressure homogenization for nanoscale cellulose fibrils and strong gels, Biomacromolecules (8), pp. 1934-1941, 2007 .
- NFC-gel (about 1-2 % solid content) was diluted with deionised water and disintegrated with Branson Digital Sonifier (Branson Ultrasonics Corporation, Danbury, USA) with an amplitude setting of 25 % for 2 minutes.
- Cationic starch (CS) with a degree of substitution of 0.035 was supplied by Ciba Specialty Chemical, Raisio, Finland. Before use, 2 g (o.d.)/I starch solution was cooked in an autoclave at 120 °C for 20 minutes.
- the water used in all the experiments was deionised water.
- sample compositions CS2.5, CS5, CS10 with fibres and cationic starch comprise different amounts of cationic starch as mentioned above.
- sample compositions NFC25 and NFC 50 with fibres and NFC comprise above mentioned amounts of NFC.
- Sample CS2.5+NFC25 comprises fibres, 25 mg/g CS and 25 mg/l NFC
- sample CS2.5+NFC50 comprises fibres, 25 mg/g CS and 50 mg/l NFC.
- handsheets were formed. Sheets were formed in a laboratory sheet former, Lorentzen & Wettre AB, Sweden (ISO 5269-1) with a 100 mesh wire. The grammage of sheets was adjusted to about 60 g/m 2 by dilution of the suspension when necessary. The sheets were wet pressed under 4.2 bar for 4 minutes and dried in a frame to avoid shrinkage during drying (105 °C for 3 minutes). The samples were conditioned according to the standard SCAN_P 2:75.
- the main objective of the above described experiments was to evaluate the effect of the modification of filler surface by NFC and CS on the fibre-filler bonding.
- Several strength properties as well as filler retention were measured for handsheets obtained after various treatments.
- Figure 2 shows the PCC retained in handsheets as a function of the added amount of PCC.
- the curves illustrate results obtained from a sheet containing no additives (reference: +) and from sheets prepared either with cationic starch alone (CS2.5: ⁇ ) or with a mixture of cationic starch and NFC (CS2.5+NFC25: ⁇ ).
- the PCC retained is obtained from the value of ash content at 525 °C.
- the combination of cationic starch and NFC (sample CS2.5+NFC25) allows a very great improvement of PCC retention.
- the amount of PCC added is about 10 times less than with combination of cationic starch and NFC than with reference.
- the retention is also significantly higher (more than twice) than that obtained by addition of starch alone.
- Figure 3 shows the tensile strength and Scott bond of handsheets as a function of filler content.
- the curves illustrate results obtained from sheet containing no additives (reference: +) and from sheets prepared either with cationic starch alone (CS2.5: ⁇ ) or with a mixture of cationic starch and NFC (CS2.5 +NFC25: ⁇ ).
- the combination of cationic starch and NFC leads to an increase in strength properties, particularly in Z-direction, as shown by Scott bond results.
- FIG. 4 shows the tensile strength of handsheets as a function the density.
- the curves also illustrate results obtained from sheet containing no additives (reference: +) and from sheets prepared either with cationic starch alone (CS2.5: ⁇ ) or with a mixture of cationic starch and NFC (CS2.5 + NFC25: ⁇ ). From Figure 4 , it can be observed that the combination of cationic starch and NFC (sample CS2.5 + NFC25) has the steepest slope. NFC is thus beneficial in maintaining the bulk.
- NFC was either mixed in the pulp together with cationic starch or added alone as such.
- the curves illustrate results obtained from sheet containing no additives (reference: +) and from sheets prepared either with two different amounts of NFC (NFC25: ⁇ and dotted line, NFC50: A) or with a mixture of cationic starch and different amounts of NFC (CS2.5 +NFC25: o and dotted line, CS2.5 +NFC50: ⁇ ).
- NFC25 ⁇ and dotted line, NFC50: A
- CS2.5 +NFC25 o and dotted line
- CS2.5 +NFC50 ⁇
- the aim of this example was to test different strategies of mixing filler and fibres with cationic starch and nanofibrillated cellulose in order to determine their influence on paper strength. Another aim was to illustrate the effect of combining NFC and cationic starch for improving the strength of filled paper in situations where fines are present.
- Dried hardwood (birch) bleached chemical pulp was also used in this example.
- About 360 g pulp was soaked overnight in 5 l of water and beaten for 50 minutes at a consistency of 1.6% in a Valley beater (ISO 5264-1) to the Shopper-Riegler (SR) number (ISO 5267-1) of about 42.
- 2 l of water was used to rinse the beater and added to the fibre suspension.
- the pulp was washed, first by acidic treatment (0.01 M hydrochloric acid) to remove metal ions, and afterwards, the fibres were converted to sodium form with 1 mM of sodium bicarbonate. After these two treatments, the pulp was thoroughly washed with deionized water.
- NFC Nanofibrillated cellulose
- the nanofibril gel was delivered at a dry content of 2%.

- PCC Commercial scalenohedral precipitated calcium carbonate
- handsheets were formed from different furnishes as in the Example 1.
- the sheet properties were measured using the same methods as presented in Example 1.
- Figures 8a and 8b show tensile strength of the handsheets as a function of filler content.
